This is interesting. The faces though, are not really that compelling. A woman sold a piece of toast with what she believed was the image of the virgin Mary on it. Moral: you see what you want to see. The image here is less likely to be natural, but it's always possible it was man on Earth. Other pyramid shapes make for some interesting theories. Long ago I read a book called The Fifth Miracle which postulated a very plausible theory that life on Earth came from Mars, transported in rock in a bacterial form, and arriving here when the Earth was basically a molten mess, but when conditions were just about stable enough to allow bacteria a reasonable chance to enjoy the hot, damp conditions. One of the theories why NASA is witholding this sort of data, is that it points to the possibility of another civilisation elsewhere in the universe. Once that happens, people begin to wonder if there is only one God, and when people are thinking freely like that they are harder to control. That's the theory anyway.
